A recent theory is that patients who require a preoperative tracheostomy have more advanced disease and may have a higher rate of occult paratracheal lymph node metastasis and thus preoperative tracheostomy increases the risk of stomal recurrence.
The right paratracheal lymph node was found to be the most frequent site of mediastinal node enlargement in adults (4).
A subsequent CT scan confirmed the finding and identified a swollen right paratracheal lymph node. The radiologist's report noted that "neoplasm cannot be entirely excluded."
